BACKGROUND OF THE INVENTION Field of the Invention

The present disclosure relates to a vibration-proof hanger and, morespecifically, to a vibration-proof hanger configured to stably andefficiently support an object mounted on one side thereof whileabsorbing vibration.

Description of the Related Art

In general, an installation device for installing a mounted object suchas a camera is a stand called a tripod, a crane equipped with a boom formounting an object, or a cradle type hanger that is installed in theshape of a cantilever on an artificial structure (e.g., a wall, aceiling, a column, etc.).

Here, in the case of the above-mentioned cradle-type hanger, it includesa boom installed in a horizontal state on the wall and a seat formounting an object, such as a camera, thereon is installed at the end ofthe boom. Moreover, the boom usually includes a single rod and hingesmounted on both ends so that both ends are rotated around the hingeswhen necessary. In other words, the boom may be rotated around thehinges if necessary to form an inclination or a level. At this time,rotation of the boom is controlled manually by loosening andre-tightening screws fastened to the hinges or is automaticallycontrolled by operation of a motor when the motor is installed in ahinge unit.

However, such a conventional cradle-type hanger has a problem in that itis inconvenient to operate the screws installed at both ends of theboom, respectively, and cannot be used in case of a motor failure. Sincethe boom includes a single rod, when external vibration is transferredto the artificial structure, the vibration is amplified by the length ofthe rod, thereby causing a problem in which a mounted object such as acamera shakes severely.

To solve such problems, the applicant of the present disclosure hasapplied for a patent for “CAMERA CRADLE” that can solve the aboveproblems with the Korean Intellectual Property Office and has beenregistered (Patent No. 10-1832935) on Feb. 21, 2018. This prior artincludes a fitting bracket fixed to a wall, an upper arm and a lower armthat allow both ends to be rotatably fixed to a mounting bracket onwhich a camera is mounted, respectively, and a tilting adjuster thatprovides the upper arm and the lower arm with a rotational forcerequired for rotation of tilting to adjust a tilting angle, and thus theangle of the upper arm or lower arm can be easily adjusted through thetilting adjuster. Moreover, the upper arm and the lower arm arerespectively installed on the upper part and the lower part of thefitting bracket and are configured to be prevented from easily movingduring vibration, and thus the vibration of the artificial structuretransferred to the upper arm and the lower arm can be suppressed as muchas possible.

On the other hand, after the application of the above-mentioned priorart, the applicant of the present disclosure filed began to study againan improved technology that can further mitigate the vibrationtransferred from an artificial structure such as a wall, and as thisimproved technology is completed, the present disclosure has applied.

The foregoing is intended merely to aid in the understanding of thebackground of the present disclosure, and is not intended to mean thatthe present disclosure falls within the purview of the related art thatis already known to those skilled in the art.

DETAILED DESCRIPTION OF THE INVENTION

Hereinafter, the vibration-proof hanger according to an embodiment ofthe present disclosure will be described with reference to theaccompanying drawings. For reference, the same reference numerals ineach drawing mean the same member.

As illustrated in FIGS. 1 to 5 , the vibration-proof hanger 1 accordingto the present embodiment may include a fitting bracket 100, a tiltingarm unit 200, a vibration-proof unit 300, and a mount 400.

The fitting bracket 100 according to the present embodiment may includea fixed plate 110 that is formed in a plate shape to allow a firstsurface thereof to be integrally fixed to an artificial structure suchas a wall, a column, a support that can be mounted on a transportationmeans by a plurality of anchor bolts 110. However, the scope of thepresent disclosure is not limited to the fixed plate 110 allowing thefirst surface to be fixed to the artificial structure by the pluralityof anchor bolts and the fixed plate 110 allows the first surface to befixed to the artificial structure by various fasteners in addition tothe anchor bolt.

Moreover, a hinge unit 120 is provided on a second surface of the fixedplate 110.

In addition, the hinge unit 120 may include an upper hinge 121 providedon the upper part of the tilting arm unit 200 side of the fixed plate110 and a lower hinge 122 provided on a lower hinge 122 provided on thelower part of the tilting arm unit 200 side of the fixed plate 110.

The tilting arm unit 200 may include an upper arm 210 allowing one endpart to be rotatably fixed to the hinge unit 120 to be tilted andallowing one end part to be rotatably fixed to the upper hinge 121 ofthe fitting bracket 100 to be titled and a lower arm 220 allowing oneend part to be rotatably fixed to the lower hinge 122 of the fittingbracket 100 to be tilted together with the upper arm 210.

The tilting arm unit 200 provides a rotational force required for therotation of tilting to at least one of the upper arm 210 and the lowerarm 220 to adjust the tilting angle of the upper arm 210 or the lowerarm 220. That is, the tilting angle (inclination angle) is adjustedwhile the upper arm 210 or the lower arm 220 is rotated by the tiltingarm unit 200.

In other words, one end (lower end) of the upper arm 210 is rotatablyfixed to the upper hinge 121 of the fitting bracket 100 and the upperarm 210 is rotatably fixed to the top hinge of the other end (top) ofthe mount 400. Accordingly, the upper arm 210 can be tilted as both endsare rotatably fixed. That is, the upper arm 210 is tilted with respectto at least one of the upper hinge 121 of the fitting bracket 100 andthe top hinge of the mount 400.

The lower arm 220 is installed parallel to the lower portion of theupper arm 210. As illustrated, the lower arm 220 allows one end part(lower end) to be rotatably fixed to the lower hinge 122 of the fittingbracket 100. The lower arm 220 is rotatably fixed to the bottom hinge ofthe other end part (upper end) of the mount 400. Accordingly, the lowerarm 220 can be tilted. That is, like the upper arm 210 described above,the lower arm 220 is tilted with respect to at least one of the lowerhinge 122 of the fitting bracket 100 and the bottom hinge of the mount400. At this time, as illustrated, both ends of the lower arm 220 arerotatably fixed to the fitting bracket 100 and the mount 400 togetherwith the upper arm 210.

The mount 400 allows, for example, a vibration-sensitive object, such asa camera CA, a measuring instrument, and the like, to be detachablymounted thereon integrally. The mount 400 is configured as a bentbracket having a cross section approximately like ‘L’ as illustrated inFIGS. 1 and 3 so that the above-described object is detachably mountedon the other side. As illustrated, the mount 400 has the top hinge andthe bottom hinge, to which the other ends of the upper arm 210 and thelower arm 220 are rotatably fixed, respectively, provided integrally onthe upper part and the lower part of one side thereof. The mount 400 maybe configured to allow the object to be mounted on the upper partthereof, but alternatively may be configured to be mounted on the lowerpart thereof. In addition, the mount 400 may be rotated with respect tothe top hinge and/or the bottom hinge as illustrated in FIGS. 15A to 15Dto be described later.

The vibration-proof unit 300 is coupled to the tilting arm unit 200 toabsorb the vibration transferred to the tilting arm unit 200 or berotated, thereby preventing the vibration from occurring in the tiltingarm unit 200. The vibration-proof unit 300 may include at least one of aabsorption-type vibration-proof module 310 coupled to the centralportion of the tilting arm unit 200 in the longitudinal direction of thetilting arm unit 200 to absorb the vibration of the tilting arm unit 200or a rotation-type vibration-proof module 320 coupled to the tilting armunit 200 and configured to be rotatable.

The absorption-type vibration-proof module 310 may include anabsorption-type vibration-proof module body 311, a vibration-proofingelastic member 312, and a coupling dial 313.

As illustrated, the vibration-proof module body 311 includes planarplates to be installed while being exposed to the outside of each of thelower arm 220 and the upper arm 210, allows grid lines to be describedlater to be marked thereon, and allows a dial cap 313 b to be describedlater to be installed therein.

The vibration-proof elastic member 312 is provided with a plurality oflayers disposed inside the absorption-type vibration-proof module body311, wherein each layer is made of a different material, and is coupledin the longitudinal direction of the tilting arm unit 200 to elasticallysupport the tilting arm unit 200. That is, the vibration-proof elasticmember 312 according to the present embodiment includes a first elasticmember 312 a forming a plurality of layers inside the absorption-typevibration-proof module body 311, and additionally includes a secondelastic member 312 b provided between the upper arm 210 and the lowerarm 220. The second elastic member 312 b is provided between the upperarm 210 and the lower arm 220 to absorb and reduce vibration that may begenerated when the upper arm 210 and the lower arm 220 are interlocked.Accordingly, the vibration-proof elastic member 312 buffers thevibration to prevent the mounted object from being vibrated.

The coupling dial 313 is coupled through the absorption typevibration-proof module body 311, the vibration-proof elastic member 312,and the tilting arm unit 200. For this coupling structure, the couplingdial 313 is configured to allow a rotary dial cap 313 b to be describedlater to move along a dial shaft 313 a to be described later. Such acoupling dial 313 may adjust the thickness of the vibration-proofelastic member 312 by movement of the dial cap 313 b. Accordingly, thecoupling dial 313 may adjust the vibration absorption amount of thevibration-proof elastic member 312 by varying the thickness of thevibration-proof elastic member 312.

The coupling dial 313 according to the present embodiment may bedual-type coupling dials 313 that are provided in a dual manner to alloweach coupling dial 313 to be faced in the center line intersecting thelongitudinal direction of the absorption-type vibration-proof modulebody 311. Each coupling dial 313 includes a dial shaft 313 a and a dialcap 313 b.

The dial cap 313 b is coupled to one end of the dial shaft 313 a and hasa scale marked in the circumferential direction of one side or the outercircumferential surface thereof to check the number of rotations. Thescale may include, for example, a second scale in which a scale having asmaller unit or a denser interval d2 than the interval d1 of theabove-described first scale is marked.

According to the present embodiment, the ratio of the interval d1 of thefirst scale and the interval d2 of the second scale is 1: 1/60 but maybe 1:½ to 1/100 if necessary. Accordingly, the coupling dial 313 mayeasily determine the thickness of the vibration-proof elastic member 312by the manipulation of the dial cap 313 b.

Moreover, as illustrated, the dial shaft 313 a passes through theabsorption-type vibration-proof module body 311, the vibration-proofelastic member 312, and the tilting arm unit 200. Since the dial shaft313 a moves up and down in the axial direction thereof when the dial cap313 b is rotated, the thickness of the vibration-proof elastic member312 may be easily adjusted by the dial cap 313 b. Accordingly, thevibration absorption amount of the vibration-proof elastic member 312 iseasily adjusted.

In the embodiment of the present disclosure as described above, thevibration-proof elastic member 312 whose vibration absorption amount isadjusted by the dial cap 313 b absorbs and buffers vibration.Accordingly, the embodiment of the present disclosure absorbs thevibration transferred to the above-described object installed on themount 400 or prevents the vibration from occurring.

On the other hand, the absorption-type vibration-proof module 310according to the present embodiment may further coupling thicknessdisplay plates 314 configured to be adjacent to or spaced apart fromboth sides of the absorption-type vibration-proof module body 311 andhaving the first scale indicating the thickness of the vibration-proofelastic member 312.

In other words, the two coupling thickness display plates 314 accordingto the present embodiment are coupled to the upper arm 210 or the lowerarm 220 to be spaced apart from the absorption-type vibration-proofmodule body 311. As such, in the embodiment of the present disclosure,the absorption-type vibration-proof module body 311 may be disposedbetween the two coupling thickness display plates 314, and the couplingthickness display plates 314 may be disposed between the absorption-typevibration-proof module body if necessary to be adjacent to or spacedapart from the absorption-type vibration-proof module body 311 to form aspace in which the vibration-proof module body 311 can move.

On the other hand, the rotation-type vibration-proof modules 320according to the present embodiment are provided in a dual manner onboth sides to be faced with each other with respect to the tilting armunit 200, thereby increasing stability. As illustrated in detail in FIG.5 , such a dual-type rotation-type vibration-proof module 320 is coupledwith the vibration-proof spring 323 to form a trapezoid when viewed fromthe upper or lower surface of the vibration-proof hanger 1 according tothe present embodiment, thereby providing effects of rolling left andright, and absorbing the vibration transferred to the above-describedmounted object of the vibration-proof hanger 1 or preventing the samefrom occurring.

In addition, each of the rotation-type vibration-proof modules 320 mayinclude: a first vibration-proof ball joint 321 including a first balljoint penetration part 321 a coupled to one end of the fixed plate 110side of any one selected from the upper arm 210 and the lower arm 220; avibration-proof rod configured to be disposed to cross the longitudinaldirection of the upper arm 210 and the lower arm 220 while allowing oneend thereof to be connected to such a first vibration-proof ball joint321; a second vibration-proof ball joint 321′ including a second balljoint penetration part 321′a while being connected to the other end ofsuch a vibration-proof rod; an auxiliary spring extension bracket 328coupled to the first vibration-proof ball joint 321 and the secondvibration-proof ball joint 321; and a snap ring 326 fixing the auxiliaryspring extension bracket 328.

Here, as illustrated in FIGS. 4 and 5 , the above-describedvibration-proof rod may be configured to include, for example, a firstrotation-type vibration-proof shaft 322, a vibration-proof spring 323,and a second rotation-type vibration-proof shaft 324. As illustrated,the first rotation-type vibration-proof shaft 322 allows one end to beintegrally connected to the above-described first vibration-proof balljoint 321 through the auxiliary spring extension bracket 328. Asillustrated, the vibration-proof spring 323 is formed of a coil springto allow one end toe be coupled to the first rotation-typevibration-proof shaft 322. As illustrated, the second rotation-typevibration-proof shaft 324 is connected to one end of the vibration-proofspring 323 while forming a line and allows the other end part thereof tobe integrally connected to the second vibration-proof ball joint 321′through the auxiliary spring extension bracket 328.

When vibration occurs, as illustrated in FIG. 5 , the vibration-proofrod moves around the first vibration-proof ball joint 321 or the secondvibration-proof ball joint 321′. At this time, the vibration-proof rodmoves smoothly as the vibration-proof spring 323 deforms. Moreover, thevibration-proof rod buffers the vibration through the self-elastic forceof the vibration-proof spring 323. Accordingly, the vibration-proof rodreduces the vibration through bending deformation orexpansion/contraction of the vibration-proof spring 323.

The snap ring 326 is detachably coupled to a snap ring coupling groove326 a formed at one end of the auxiliary spring extension bracket 328 toprevent the auxiliary spring extension bracket 328 from being separatedfrom the first ball joint penetration part 321 a or the second balljoint penetration part 321 a′.

The auxiliary spring extension bracket 328 is coupled to the firstrotation-type vibration-proof shaft 322 and/or the second rotation-typevibration-proof shaft 324 of the above-described vibration-proof rod tostably support the first rotation-type vibration-proof shaft 322 or thesecond rotation-type vibration-proof shaft 324.

On the other hand, other embodiments of the present disclosure shown inFIGS. 6 to 11 are different from the above-described embodiments in thata plurality of above-described vibration-proof rods is included and aspring extension bracket 327 is included.

As illustrated, the embodiments of the present disclosure may beconfigured to include a spring extension bracket 327 in each of therotation-type vibration-proof module 320 and may be implemented byremoving the spring extension bracket 327 as in the above-describedembodiment. For convenience of description, only the spring extensionbracket 327 will be described below.

The spring extension bracket 327 is provided with a plurality ofvibration-proof shaft coupling holes 327 a to which the plurality ofabove-described vibration-proof rods are coupled respectively. In otherwords, the spring extension bracket 327 is fixed by inserting the firstrotation-type vibration-proof shaft 322 and the second rotation-typevibration-proof shaft 324, which form both ends of the plurality ofvibration-proof rods, into the vibration-proof shaft coupling hole 327a.

As such, the spring extension bracket 327 allows the number ofvibration-proof rods to be adjusted according to user convenience toefficiently absorb and prevent the vibration that may be transferred tothe above-described mounted object. That is, in another embodiment ofthe present disclosure, as illustrated in FIGS. 4 and 5 , a plurality ofabove-described vibration-proof rods may be configured as needed. Thenumber of such vibration-proof rods may be determined according to theamount of vibration to be absorbed.

In the embodiment of the present disclosure as described above, asillustrated in FIGS. 8 and 9, as the spring extension bracket 327 rollsaround the first vibration-proof ball joint 321 or the secondvibration-proof ball joint 321′, the above-described vibration-proof rodabsorbs the vibration while moving in a torsional manner. At this time,the vibration-proof rod moves smoothly as the vibration-proof spring 323deforms. The vibration-proof rod buffers the vibration by theself-elastic force of the vibration-proof spring 323. Accordingly, thevibration-proof rod reduces the vibration through bending deformation orexpansion/contraction of the vibration-proof spring 323.

According to the present embodiment having the structure and action asdescribed above, the mounted object may be stably and efficientlysupported while the vibration is absorbed, and in particular, thevibration transferred to the fitting bracket or the tilting arm unit maybe suppressed and mitigated as much as possible.

On the other hand, as illustrated in FIGS. 12 to 13 and 19 to 21 , theabove-described coupling dial 313 allows any one of dial caps 313 b tobe mounted on one end part (one side) of any one of a pair of spaceddial shafts 313 a by screw coupling. As illustrated, the coupling dial313 allows the other dial cap 313 b to be mounted on the other end part(opposite side) of the remaining dial shaft 313 a by screw coupling.That is, since the pair of dial caps 311 b are respectively mounted onopposite ends of the dial shafts 313 a as illustrated, they face eachother at opposite positions.

As each of the dial caps 313 b is mounted as described above, when beingindividually operated, each of the dial caps 313 b moves along the dialshaft 313 a at the opposite positions and presses the absorption-typevibration-proof module body 311 to shrink the vibration-proof elasticmember 312. At this time, the dial caps 313 b respectively press theabsorption-type vibration-proof module body 311 in opposite directions.Accordingly, only the portion adjacent to the operated dial cap 313 b ofthe vibration-proof elastic member 312 is shrunk and deformed to athickness suitable for vibration absorption. That is, the thickness ofthe vibration-proof elastic member 312 is adjusted by the dial cap 313b.

Here, the above-described absorption type vibration-proof module body311 may be formed of a substantially rectangular plate through which aplurality of dial shafts 313 a pass together as illustrated in FIGS. 1and 3 but may be alternatively formed of a plate through which only oneof the dial shafts 313 a passes as illustrated in FIGS. 12 to 13 and 19to 21 . As illustrated, the absorption-type vibration-proof modulebodies 311 are respectively installed on the upper arm 210 and the lowerarm 220 of the tilting arm unit 200 in an opposite state together withthe dial cap 313 b.

When the absorption-type vibration-proof module body 311 is configuredas described above, each vibration-proof module body 311 presses therespective vibration-proof elastic members 312 while being pressed bythe opposite respective dial caps 313 b, thereby adjusting the thicknessof the vibration-proof elastic member 312. Accordingly, suchabsorption-type vibration-proof module bodies 311 prevent the pressingforce transferred when one of the dial caps 313 b is operated from beingtransferred to the other dial cap 313 b.

For example, since the vibration-proof module body 311 of FIGS. 1 and 3described above is formed of a single plate to allow a plurality of dialcaps 313 b to be installed therein while being spaced apart, thepressing force by any one of the dial caps 313 b is transferred to thevibration-proof elastic member 312 in which the remaining dial cap 313 bis disposed. Accordingly, the above-described vibration-proof modulebody 311 cannot precisely adjust the thickness of the vibration-proofelastic member 312. However, as described above, when thevibration-proof module body 311 is configured to be installed in anopposite state, it is possible to prevent the pressing force transferredfrom one vibration-proof module body 311 from being transferred to theremaining vibration-proof module body 311, and thus the thickness of thevibration-proof elastic member 312 may be precisely adjusted to adesired thickness.

On the other hand, the above-described vibration-proof elastic member312 may be divided as illustrated in FIGS. 12 to 13 and 19 to 21 to beconfigured in plurality. As illustrated, the vibration-proof elasticmember 312 is configured by being divided into a number corresponding tothe number of the dial shaft 313 a or the dial caps 313 b. Asillustrated, each of the divided vibration-proof elastic members 312allows the pair of dial shafts 313 a to be passed therethrough. Sincethe divided vibration-proof elastic members 312 are physically separatedas illustrated, the pressing force by the dial cap 313 b does notinterfere with each other even when the dial cap 313 b coupled to eachdial shaft 313 a is operated. Accordingly, the thickness of each of thedivided vibration-proof elastic members 312 is precisely adjusted.

On the other hand, the above-described mount 400 installed on thetilting arm unit 200 may be configured as a bent bracket as illustratedin FIGS. 1 and 3 but may be differently configured as a planar bracketshown in FIGS. 16A to 18C. As illustrated, the planar bracket may beformed of, for example, a substantially rectangular or square plate. Asillustrated, the mount 400 is provided with a yoke 4000 a to which ahinge is coupled in a penetrating state and a bearing may be mountedinside the yoke 400 a. In conclusion, as illustrated in FIGS. 15A to16B, the mount 400 may be configured as the above-described planar orbent bracket according to the characteristics of the object mounted onone side surface thereof.

Here, in at least one of the tilting arm unit 200, the mount 400, andthe fitting bracket 100 described above, a vibration reduction unit maybe integrally provided to reduce vibration. That is, the vibrationreduction unit may be integrally provided in the upper arm 210 and thelower arm 220 of the tilting arm unit 200, the bent or planar bracket ofthe mount 400, and the fixing plate 110 of the fitting bracket 100.

The vibration reduction unit reduces the cross-sectional area of theabove-described component to which the vibration is transferred, therebyreducing the vibration transferred to the above-described component. Forexample, as illustrated in the enlarged view of FIG. 14 and FIGS. 19 to21 , the vibration reduction unit may be configured as a slit-shapedgroove that is formed in the shape of a groove in the above-describedcomponent by extrusion to reduce the cross-sectional area of theabove-described component. Since the cross-sectional area of the portionwhere the slit-shaped groove GR is formed is reduced in theabove-described component, the vibration is not transferred to theportion where the slit-shaped groove GR is formed. Accordingly, theslit-shaped groove GR reduces the vibration transferred through theabove-described component.

When the slit-shaped groove GR is not prepared in the above-describedcomponent, the above-described component is thickened so that thevibration is completely transferred. However, when the slit-shapedgroove GR is prepared in the above-described component, there is nomedium for transferring the vibration to the portion where theslit-shaped groove GR is formed, and thus the vibration does nottransfer. Accordingly, the transferred vibration is reduced in theabove-described component.

In such a component, even when the slit-shaped groove GR is formed, onlythe thickness of the portion where the slit-shaped groove GR is formedis reduced, and the thickness of other portions is not reduced, so thatthe designed strength can be maintained.

The vibration reduction unit may be configured as a through-hole 400 bas illustrated in FIGS. 17A to 18C. Such a through-hole 400 b isolatesthe vibration transferred to the above-described component to reduce thevibration. The through-hole 400 b may be provided together with theabove-described slit-shaped groove GR to double vibration reductioneffect.

In the embodiment of the present disclosure as described above, sincethe pair of dial caps 313 b are installed in each absorption-typevibration-proof module body 311 in opposite states, the pressing forceof the dial cap 313 b is applied to each vibration-proof module body311, and the dial cap 313 b is exposed even when the fixing plate 110 ofthe fitting bracket 100 is installed on a structure such as a wall, sothat the dial cap 313 b can be easily operated.

In addition, since the absorption-type vibration-proof module body 311is configured in a number corresponding to the number of the dial caps313 b to allow each dial shaft 313 a to be installed therein in apenetrating state, it is possible to prevent the pressing force by anyone of the dial caps 313 b from being transferred to the other dial cap313 b or the elastic member 312.

Moreover, when the vibration-proof elastic member 312 is divided into aplurality of parts, it is possible to prevent the pressing force by thedial cap 313 b from being transferred to each of the vibration-proofelastic members 312.

Moreover, when the mount 400 is provided on the tilting arm unit 200,the mounted object such as a camera CA may be easily installed on themount 400.

In addition, when a groove-shaped vibration reduction unit is provided,it is possible to reduce the vibration transferred to the tilting armunit 200, the mount 400, and the fitting bracket 100 and, morespecifically, when the vibration reduction unit is configured as theslit-shaped groove, it is possible to easily configure the vibrationreduction unit.
